I'd intended to purchase this early on to do my part to show there's a market for fighters on the PC, but I feel bad that I've had to push it back due to other releases. $13.49 is tempting but the deal couldn't have come at a worse time, haha.
I'm torn myself. I just spent $30 on Bioshock Infinite and I went kinda crazy in the summer sale.
edit: I don't really like fighters anymore but MK9 is sublime.
I personally think this is a better deal: http://www.amazon.com/dp/B00ECGPL5W/?tag=neogaf0e-20
As you could sell the Batman and LOTR games for $5 each on steam at the very least and you get the mortal kombat arcade kollection for a few quid cheaper.
It totally is. I have all those games though (except MK Arcade) and don't want to go through the hassle of reselling them.
But for anyone whom that doesn't apply to: totally a better deal. Totally.
